H370 Mining Master is the world's first mining motherboard that supports up to 20 graphics cards. With 20 PCIe-over-USB ports onboard and triple ATX12V plugs for connecting up to three PSUs simultaneously to power the motherboard, H370 Mining Master lets you run up to 20 NVIDIA and AMD GPUs in parallel to max out the megahash rate.

USB Ports for PCIe Riser Cards

Simplified connectivity

GPU risers for mining systems typically consist of three pieces: the x16 slot for the graphics card, the PCIe x1 card that plugs into the motherboard, and the connecting USB cable. H370 Mining Master simplifies this chain with PCIe x1 slots featuring banks of vertical PCIe-over-USB ports that let riser cables plug directly into the motherboard.
This direct connection is sturdier than using a PCIe card, with less chance of inadvertent disconnects. It also reduces the total number of parts in your farm and cuts down on clutter for cleaner wiring.

Triple-ATX12V Power Delivery

Engineered to deliver the power your graphics cards need

H370 Mining Master is engineered to provide all the power your GPUs demand, cleanly and efficiently. The 20 onboard USB ports for PCIe riser cards are grouped into three distinct zones, each powered by its own dedicated 24-pin ATX12V power connector. The ATX12V power connector reduces wiring complexity and ensures ample power delivery to all PCIe slots.

Easy-to-troubleshoot

GPU State Detection and Farm-Friendly Labels

Easy management and debugging

GPU State Detection scans the system at boot and indicates whether each riser port is empty, connected to a functional graphics card, or experiencing problems. The updated State Detection GUI clearly identifies the location and status of each port along with the alphanumeric code that identifies it.
To further streamline troubleshooting, the board will ship with matching Farm-Friendly labels, which can be affixed to corresponding riser cards. You'll be able to quickly look at the labels to find flagged GPUs instead of being forced to trace the path of cables connected to affected ports.

Onboard debug LEDs

Easy diagnostics

Onboard diagnostics are augmented by individual debug LEDs that illuminate when there are problems with specific system components, like the CPU or memory. A two-digit POST code display identifies issues that interrupt the boot process, further simplifying the troubleshooting process, while integrated power and reset make it easier to work with a bare board.
